Easily the most luxurious resort in St. Martin, the 55-acre La Samanna resort brings tranquility to an otherwise tourist-filled island. Featuring two beautiful pools, an extensive wine cellar, a yoga and Pilates studio, a European-style spa, and the island's most pristine beach, this 81-room, eight-villa retreat is hard to beat. The vibe is about as fancy as it gets for St. Martin, so of course everything -- from the nightly rates to the dinners and spa treatments -- comes at a sky-high cost.
